MACHINE FOR DESTROYING COTTON-BOLL WEEVILS.

To all whom it may concern:

Be it known that l. Loris Nnacxssn PRUnrio'MMn, a citizen of the United States. residing at Bermuda. in the parish of Xatchitoches and State of Louisiana, have invented certain new and useful improvements in Machines for Destroying (otton Boll \Veevils. of which the following is a specification. I

My invention relates to improvements in machines for destroying cotton boll-weevils. the primary object of the invention being to provide means whereby the. poison. in either powdered or liquid form. may be properly and expeditiously distributed ,upon the rows of growing cotton stalks during the various stages of growth subjected to the ravages of this insect pest.

The invention relates more particularly to the construction of the poison containing and distributing -mechanism wherehy the same may be adjusted vertically on the carriage to accommodate the same to the height of the cotton stalks during the various sta 'es of growth and means for regulating the (istribution of the poison to meet various conditions.

lVith the above mentioned ends in View, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims. (I

Referring to the drawings, forming a part,

of this specification, Figure 1, is a perspective view of a machine constructed in accordance with my invention. Fig. 9., a detail side elevation of one of the improved distributing container-drums. Fig. 3, a

cross sectional view of the same, showing the position and arrangement of the internal agitators. Fig. 4, a detail view of a modified form of nozzle attachment.

Similar numerals of reference designate like parts throughout all the figures of the. drawings.

The improved machine comprises a suitable supporting carriage or frame 1, carried upon a pair of carriage wheels 2, said car.- riage wheels 2, in the present instano 'beihg mounted upon a transversely disposed yoke or arched. axle member 3. The side members of the carriage frame 1, are provided with Specification of Letters Patent.

Patented Jan. 18, 1910. 1909. serial No. 496.362.

upwardly extending standards it, provided witha series of bearing openings 5, for receiving and containing the transversely disposed overhanging driving shaft 6.' The driving shaftti, is provided with a plurality of poison distributing container-drums 7. said container drums being adapted to be adjusted upon the driving shaft 0. to'conform stalk-s by being adjustably mounted and secured thereon by means of adjusting bolts 8.

The driving shaft (3. is provided. in the present instance. with a pair of sprocket wheels 9. carrying a pair of sprocket'chains 10, passing over a pair of sprocket wheels 11, beneath. The sprocket driving'wheels 11, are carried upon and secured to the inner sides of the carriage wheels 2, by means of ratchet.mechanism (not shown) in a well known manner, said 'atchet mechanism being mounted within a casing-or housing 11, as shown, whereby motion is independently transmitted from the several carriage wheels to the driving shaft, and providing for the turning of the carriage to meet the demands of actual'service.

The driving shaft 6, together with the attached container drums 7, are adapted to be adjusted vertically upon the carriage to conform to the height of the rows of cotton stalks beneath, by passing the driving shaft through suitable bearing openings 5, in the standards, said shaft when so adjusted being secured as against lateral displacement by means of bearing collars 12. The length of the sprocket chains 10, may be correspondingly regulated, it being evident that, if desired, motion may be transmitted to the driving shaft 6. by a single sprocket chain. and pair of sprocket wheels.

The machine may be drawn by one or two horses or mules and, if desired, additional container drums may be mounted upon the'driving shaft 6, and the frame of the machine correspondingly widened.

In the embodiment of the invention shownin Fig. 1, of the drawings, two rows of ously treated, the carriage wheels being adapted to pass just within and between the two adjacent rows of cotton stalks, the container drums 7, projecting or extending out laterally on the outer sides of the carriage wheels so as to distribute the poison to the distance between the rows of cotton.

cot-ton stalksare adapted to be simult-aneteen shaped direct-l to the rows of cotton stalks passing beneat 1. Each'distributmg container drum comprises a hollow disk-shaped body or canportionprovided with an axle sleeve 13, an

is provided with radially extending agitator arms or wings l4, The poison is adapted to be introduced into the container drums 7, throughan inlet opening 15, normally closed by means of a screw cap 16. Each container drum is provided about its periphery or outer rim portion with a plurality or series of radially extending spraying or distributing nozzles 17 the amount of material distributed through said nozzles being adapted to be regulatedby means of the slidably mounted valve plates 18, carried upon the periphery of the container drums and adapted to open or close the openings of the neck portions 1'7, of the distributing, nozzles. the poison may-also be regulated by regulating the size of the openings in the nozzles, and, if desired, the movably' secured and attached as indicated in Fig. 4, by'screw threading thesame upon separately formed neck such be attached-and brought into service to meet .the demands of the occasion.

' From the foregoing description, talien in connectlon with the accompanying draw-v,

ings, the operationand advantages of my invention will be readily understood.

as a means for agitating the poison wlthm the containers each axle sleeve nozzles 17 may be re-,

portions 17 .v In instance nozzles of varying sizes may- Having thus described my invention, what The distribution of L distributing container-drum com I claim and desire ent is, I

1., In a machine of the class described, a rising a hollow disk-shaped body provide with an axle-sleeve and a plurality of valved peripherally-arranged nozzles,

to secure by Letters Patdisk-shaped body. I

2. In a machine of the class described, a

, distributing container-drum comprising a and agitators -carried by said axle-sleeve within said hollow adapted to open and close theoutlet openings of said nozzle-necks, and agitator "wings carried by said axle-sleeve within Said -con-' tainer-drum.

3. In a machine vof the class described, a.

supporting frame mounted on vehicle wheels and carrying an overhanging drivings'haft, I container drums adjustablymounted on saiddriving shaft, and provided with a plurality of valved peripheral nozzles, agitators mounted within said container-drums, and means'for revolving said overhanging driving shaft from one of said vehicle wheels.

In testimony whereof I have ailixed my signature, in presence of two witnesses.
